This skill enforces rules for building production-quality PyQt6 desktop applications. The core principles are: strict MVC separation via signals/slots, never blocking the UI thread, centralized theming via QSS, and layout-manager-driven responsive design. These rules prevent the most common PyQt6 failures: frozen UIs, untestable coupling, and platform-specific rendering bugs.
